Refractory gold ore pretreatment Treatment of refractory gold ore (whole ore and flotation concentrates) has become more prominent since the 1980s, with many gold discoveries often including ores that are wholly or partially refractory. Refractory pretreatment processes include pressure oxidation, biological oxidation and various forms of

REFRACTORY GOLD. By definition, refractory gold ores contain gold that is resistant to extraction by conventional chemical processing and as a result responds poorly to traditional gold cyanidation techniques such as CarboninLeach (CIL), yielding less than 80% of the contained gold.

Refractory gold ore refers to the part of gold ore that cannot be extracted effectively by the conventional cyanide leaching process after the fine grinding. The gold in this type of gold ore cannot contact with the cyanide solution due to physical encapsulation or chemical combination, resulting in a very low gold leaching rate. Therefore, how can we improve the gold leaching

Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets.

Gold ore can be classified as freemilling, complex, or refractory and each type of ore has different challenges when it comes to processing methods. Cyanidation with CIL/ CIP continues to be the most common method, although there are environmental concerns due to toxicity. As mining companies continue to face pressure to reduce environmental impact, and as freemilling ores become less and

For processing the deposits that contain refractory gold ore, a separate ROT plant with a nominal capacity of Mt/y will be installed adjacent to the existing Sabodala plant, with processing expected to begin in 2023. The ROT design is based on the use of bacterial oxidation (BIOX® technology) to expose the gold that is occluded within sulphide minerals, which then allows for gold

· The term "refractory ore" is used to classify different gold ores that are not amenable to the traditional cyanidation processes. Gold in refractory sulfide ores occurs as fine inclusions or in solid solution typically within pyrite, marcasite, and arsenopyrite grains. In this type of ore, because the gold is encapsulated, the interaction with cyanide to form the soluble metal complex is

Whether gold is refractory or nonrefractory has a huge bearing on a potential mine''s viability. A deposit with a resource similar or larger than that of existing mines, could be rendered unviable if testwork identifies that the ore is refractory. This means that when looking at resources a company maybe quoting, it is not enough to take note of the grade, but we must consider the processing

Flotation and subsequent processes (refractory ore processing) The flotation process is described in detail in chapter Native gold, gold tellurides, and sulphides that contain finely disseminated gold can be floated and recovered in a concentrate. In gold metallurgy flotation is often used as a preenrichment process for refractory ores.
